In California, you can legally wear reflective ankle bands in lieu of pedal reflectors, but you have to do one or the other. Makes sense to me.
Also lost pedal reflectors when my SL got new pedals, and no good way to add them. So I went the velcro ankle band route. Way more visible than pedal reflectors — especially from the side. Also weigh nothing and take up very little space in my limited onboard storage.
Then I found inexpensive reflective LED slap bands on Amazon. Quite a light show at night! A little heavier and bulkier, but easy-on, easy-off with good coin battery life.
After the last night ride you posted, I'd say you should look into these solutions.
